Define the three formats by classroom access
Full-day integration usually follows more normal classes and routines; partial integration joins selected classes or mornings while language support or activities fill the rest; a standard study tour uses its own classes and group activities. Ask the school to state actual weekly classroom hours, not only a product name.
Match academic load to current ability
Conversational English does not equal understanding a science lab, history discussion or written task. Full-day access needs more independent listening and adjustment; partial integration can test real classrooms first; a standard tour suits language, activities and care-focused goals.
Compare energy use across one real day
Put commute, early class, lunch socialising, homework, sport and evening residence rules on one timeline. If the student is exhausted every evening, more classroom hours may not mean more learning; a partial format can leave room to process language and rest.
Use observable outcomes before stepping up
Set two-week behavioural goals such as reaching class independently, understanding one assignment or joining one group activity. Discuss the next stage after evidence appears, rather than promising long-term full-day placement at payment.
